Patent CA-2299947-A1 (CA)
Title: The application of error correction coding to transmission equipment protection
Inventor: DAVE BHARAT P
IPC: H04L1/22
Filed: 2000-03-03
Abstract: Error control coding is applied to data streams transmitted through transmission equipment such as a telecommunications switch having a distributed synchronous switch fabric. Each k-symbol dataword is encoded to generate an n-symbol codeword that is then sliced for transmission through the transmission equipment. After routing, error-correction decoding is applied to the resulting routed n-symbol codeword to detect and correct one or more errors in the codeword to generate a k symbol routed dataword that is identical to the original incoming dataword. Depending on the coding scheme, different types and numbers of errors can be corrected in each codeword. For example, for Reed-Solomon [12, 8, 5] coding with Galois field (2 4), corrections can be made for up to four erasures with no random errors, up to two erasures and one random error, or up to two random errors with no erasures. In this way, error-less fault tolerance can be provided that ensures the accuracy of transmission processing in the event of certain combinations of errors. Preferred embodiments involve temporal sharing of components (for more cost effective implementations) and shuffling of data (to increase error-correction coverage).

Abstract: La présente invention concerne un procédé et un appareil utilisant une réalité virtuelle affichée sur un écran (12a) pour présenter un stimulus de test constitué d'une première couleur superposée sur un fond d'une deuxième couleur, en vue de tester et de quantifier des informations visuelles provenant de l'oeil, du système visuel et du cerveau. Une configuration de casque (12) permet au patient d'observer un champ de vision dans lequel des stimuli de test séquencés sont présentés par un dispositif d'excitation commandé par un ordinateur (13). Des retours sensoriels interactifs vers le patient et provenant de celui-ci permettent de mettre en oeuvre une présentation et une modulation de stimuli de test commandées par ordinateur en vue de mesurer avec précision des paramètres tels que la performance de champ visuel, l'acuité visuelle et la vision des couleurs. Le système offre au patient une liberté de mouvement sans précédent de la tête et du corps, ce qui permet de réduire au minimum ou même d'éliminer la tension et la fatigue observées habituellement avec des systèmes classiques de test de champ visuel à réalité non virtuelle.
